Title: Valve for controlling a reversible rotary hydraulic motor
IPC: F16K11/02
Filed: 1975-04-25
Abstract: 1487287 Valves DEERE & CO 25 April 1975 [26 April 1974] 17332/75 Heading F2V In a valve for controlling the flow to and from a reversible rotary motor 50, a pair of bores 18, 20 house similar valve units and have recesses 26, 28 connected to opposite sides of the motor and recesses 30, 32 connected to a pressure source 52. In each valve unit a restriction between the ends of a split ring 90 allows the fluid pressure to equalize on opposite sides of a piston 88 so that a closure member 98 thereon closes the communication between inlet recesses 30, 32 and recesses 26, 28 which are connected to work ports 40, 36 respectively. Metering grooves 108 on a further closure member 106 communicate the recesses 26, 28 with a reservoir space 16. On energization of an electromagnetically actuated pilot valve 114, 122, a plunger 118 communicates the chamber below the piston 88 with the reservoir space 16 so that pressure in the recess 30, 32 opens the respective valve member 98 to connect the recesses 30, 26 or 32, 28 via metering grooves 102 on the valve member 98 and closes the communication between the recess 26 or 28 with the reservoir space 16. The motor is thus driven in one direction and can be reversed by actuation of the other pilot valve.

Abstract: 712,375. Switches held set and freed mechanically. GENERAL ELECTRIC CO. July 11, 1952 [July 11, 1951], No. 17552/52. Class 38(5) [Also in Group VI] In an electric toaster (see Group VI) having an electric motor to drive the toast carriage to its toasting position and time the toasting, toasting is initiated when the circuit to the motor and heating elements is closed by a conducting bridging member 43 engaging contacts 38, 41. Bridging member 43 is carried'by an arm 44 secured to a bracket 45 mounted on the base of the toaster. A link 46 is pivoted on bracket 45 having, at its lower end, a roller 48 and being pivoted at its upper end to a bell crank lever 37 operated by portion 35 so that on pressing portion 35 down, Fig. 3, roller 48 engages arm 44 to cause member 43 to engage contacts 38, 41. When the carriage reaches toasting position a projection 50 on the carriage engages the end 51 of bell crank lever 37 to disengage roller 48, Fig. 4, and, at the same time, a depending member 49 on the toasting carriage engages the outer'end of arm 44 to retain member 43 in position on contacts 38, 41. When the carriage reaches its toasting position, the drive from the motor is disconnected and the timing gear is connected to gearing driven by the motor. After a predetermined time a pin on the timing gear causes the carriage to be released and hence member 49 is removed to allow member 43 to rise and open the circuit. A bimetallic strip is arranged to reduce the toasting time as the toaster heats up.

Filed: 1952-09-26
Abstract: 774,076. Earth-drilling bits. HAWTHORNE, H. J., and WEAVER, E. M. Sept. 26, 1952, No. 17665/54. Divided out of 774,075. Class 85. Each radially extending cutter blade of an earthdrilling bit has a plurality of cutting fingers 50 stepped upwardly and outwardly from the axis of the bit. Stiffening ribs 60 may be formed behind the fingers, the forward and outward surfaces of which can be formed by a hard metal coating. The disposition of the fingers on the blades can be varied so that when several blades are mounted on a bit body some of the fingers track one another, whilst other fingers chip away the upstanding material left by the tracking fingers. The cross-section of the fingers and the thickness of the hard metal coating increases as the distance at which the fingers are situated from the axis of the bit increases. The lower end of each finger is defined by a vertical edge and an edge that slopes upwardly and inwardly. The means for clamping the blades on to a bit body forms the subject matter of Specification 774,075, which together with Specification 774,077 is referred to.

The baffle 6 is made of fire-brick or other refractory material, and the mixing-chamber 2 is provided with a fire-proof lining 7.
Patent GB-313536-A (GB)
Title: Improvements in or relating to the recording of sound on films and in the reproduction of recorded sounds
Filed: 1929-06-13
Abstract: 313,536. Telefunken Ges. f³r Drahtlose Telegraphie, (Assignees of Karolus, A.). June 13, 1928, [Convention date]. Optical apparatus; electric circuit arrangements.-Sound is recorded photographically upon a film by dividing up the whole frequency range to be recorded into two or more bands of frequencies, which are separately and simultaneously recorded in strips side by side upon the film, reproduction being effected simultaneously from these separate frequency-band records, using either a single photo-electric cell and loud. speaker, or separate cells which control individual loud-speakers or a common one. The light slits used in the recording and reproducing apparatus may be chosen in width to suit the bands of frequencies dealt with, a narrower slit being used for the higher frequencies than that used for the lower. Preferably, in recording, the amplitude of the higher frequencies is increased, relatively to the low-frequency amplitudes, and the original relationship between the amplitudes of the various frequency bands is restored during reproduction. This restoration may be effected by suitable selection of the widths of the apertures when reproducing, by varying the light intensity, or by selective amplification. In the recording apparatus shown in Fig. 1, two Kerr cells 6, 7 are employed, each being associated with a light source 12 or 13, an optical system comprising polarizers 8 or 9, and analyzers 10 or 11, and suitable lenses, and a slit 20 or 21, the slit 20 through which light that passes through the cell 6 is transmitted to the film 24 being narrow compared with the slit 21 associated with the cell 7. The recording microphone 1 is connected to an amplifier 2, the output circuit of which is branched, one branch including a filter 3 and an amplifier 5 connected to the cell 6, and the other branch including only an amplifier 4 connected to the cell 7. The filter 3 prevents the passage of low-frequency oscillations, so that by this arrangement the higher frequencies, strongly amplified, are recorded by the light passing through the cell 6 and the narrower slit 20, while the lower frequencies are recorded with less amplification by the system comprising the cell 7 and wider slit 21. Fig. 2 shows apparatus for reproducing sound from the double record. In this arrangement, slits 31, 32 of different widths are used for illuminating the separate frequency-band records, and the transmitted light affects separate photo-electric cells 33, 34. These are connected, the one to an amplifier 35, and the other to an amplifier 36 and " regulating device " 37, the two sets of oscillations being combined by a common amplifier 38 which operates a loud-speaker 39. The invention may be applied to the production of and reproduction from records not only to the kind in which the sound-trace is of uniform dimensions and of varying opacity, but also to other kinds such as those in which a blackemed band of varying width is made on the film.

The networks may be of square mesh, as in Fig. 1, in which case the arms of the V-shaped jointing members are at 45 degrees or 90 degrees, according to the number of bars or elements at a junction. The networks may be of hexagonal mesh, in which case the arms of the V-shaped jointing members are at 60 degrees or 120 degrees. A 90 degrees jointing member is indicated in Fig. 9. The jointing members are stiffened by flanges and may be of cast or pressed metal, plastic or cement. Where a framework comprises booms 12, 14 (Fig. 8) and networks 13, 15 in planes at right angles to that containing the booms V-shaped jointing members are used, and in addition a continuous boom 14 is formed of two bars and the inclined bars 13, 15 are held between them (Fig. 9). The Specification as open to inspection under Sect. 91 describes the use of V-shaped jointing members in building panels and describes an arch constructed of frameworks formed of connected networks. This subject-matter does not appear in the Specification as accepted.
